[architecture] High-confidence hallucinations in agent outputs execute autonomously without human verification

Require agents to output a confidence score or use logprobs alongside structured data, and route to a human-in-the-loop \(HITL\) checkpoint if the score is below a calibrated threshold.

Journey Context:
Agents often hallucinate but sound confident. Relying solely on the LLM's self-reported confidence is flawed, but combining it with structural checks \(e.g., 'Did I find the exact database record?'\) works better. The tradeoff is that HITL introduces latency and breaks full autonomy, but it acts as a necessary circuit breaker for high-stakes operations where the cost of an error exceeds the cost of delay.
